THERMOSTAT PROBE PACKAGES: FAST RESPONSE, TINY STAT TM

Transcription

1 THERMOSTAT PROBE PACKAGES: FAST RESPONSE, TINY STAT TM Introduction Klixon 3BT Tiny Stat fast response temperature probes are designed to provide reliable, consistent performance over a long cycle life in the harshest environments. These probes provide rapid response times combined with outstanding shock and vibration resistance. They have a wide operating temperature range of 0 F to +350 F. These characteristics enable protection or indication of high or low temperatures in aircraft environmental control systems, helicopter gear boxes, compressor discharge gas streams, and coolant systems. Features Hermetically Sealed (probe only) Snap-action switching Pre-set, non-adjustable calibration High resistance to shock and vibration Qualified to MIL-PRF-24236/11 PERFORMANCE Contact Ratings (Resistive) Based on standard differential 30 VAC/DC 115 VAC Life Cycles Contacts 1.0 Amperes 1.0 Amperes 10,000 Silver 0.5 Amperes 0.5 Amperes 10,000 Gold Vibration 10 to 2,000 Hz, 30 G. Notes: 1.) Devices which open on temperature rise should not be subjected to vibration while at temperatures of 75 F or more below the opening temperature. 2.) Devices which close on temperature rise should not be subjected to vibration while at temperatures of 75 F or more above the closing temperature. Characteristics Contact Resistance Dielectric Strength Operating Temperature Range Ambient Temperature Range Operating Temperature Tolerances Differential ohms max., (0.150 ohms max. for close on rise devices with setpoints greater than 175 F) per MIL-STD-202, Method 307 Contact resistance shown is for the 3BT thermostat and does not include resistance of wire leads or connector VAC, rms, 60 cycles for 1 minute (leads to case), per MIL-STD-202, Method F to 350 F (-17.8 C to C) -80 F to 400 F (-62.2 C to C) ± 10 F (± 5.6 C) between opening and closing temperatures: 30 F (16.7 C) Page 1
